A kind of aqueous matt canvas of Freehandhand-drawing and preparation method thereof
Technical field
The present invention relates to canvas technical fields, more particularly, to a kind of matt canvas for Freehandhand-drawing.
Background technology
Existing Freehandhand-drawing painting canvas, water imbibition is poor, easily turns to be yellow, and is easy wrinkle, it is not easy to preserve, be also not suitable for outdoor suspension, quilt
Drenching with rain to attend the meeting makes picture fade.For this reason, it is necessary to improve existing Freehandhand-drawing picture carrier.There is document report in chemical & blended fabric, glass-fiber-fabric
Or adhere to the faces PVC on cotton or prepare the production technology of painting canvas using the latex composite compounding of various polymer, or use terylene material
Matter scrapes the production technology that PVC coatings prepare similar canvas material with knife.The major defect of this two methods is in base fabric
After covering PVC film or imposing on polymer emulsion, effect is smooth, though air brushing painting canvas is can be used as, for Freehandhand-drawing painting canvas, it
The skin texture of base fabric itself cannot be embodied, expression effect is greatly reduced.
Invention content
In view of the above-mentioned problems existing in the prior art, the applicant provides a kind of aqueous matt canvas of Freehandhand-drawing and its system
Preparation Method.The present invention has reformed traditional hand design canvas material and method for mounting, has opened up the frontier of weaven goods application.
Technical scheme is as follows:
A kind of aqueous matt canvas of Freehandhand-drawing, preparation method include the following steps:
(1) gel resin layer material:By 1~3 part of trimethylolpropane trimethacrylate, 1~2 part of epoxy acrylate is anhydrous
2~3 parts of elder generations of ethyl alcohol uniformly mix, and then with 20~24 parts of acrylic ester adhesive, 20~22 parts of starch, 5~8 parts of alum goes
It is stirred evenly after 10~14 parts of mixing of ionized water;
(2) base coating material:By 5~7 parts of silica, 30~32 parts of calcium carbonate, 10~15 parts of titanium dioxide, acrylate
20~23 parts of adhesive, 2~3 parts of brightener stir evenly after 20~25 parts of mixing of deionized water;
(3) topcoat material:By 10~12 parts of calcium carbonate, 20~23 parts of silica, 15~18 parts of deionized water, third
10~13 parts of olefin(e) acid ester adhesive stirs evenly after 4~5 parts of mixing of surfactant;
(4) calendering processing first is carried out to fabric, then sprays gel resin layer, baking oven drying is carried out after painting;
(5) spraying bottom coating on gel resin layer is dried using baking oven after painting, then carries out heating calendering;
(6) finishing coat is sprayed on priming coat, is dried using baking oven after painting, and calendering processing is then carried out;
The number of each raw material is parts by weight.The fabric uses polyester-cotton blend or cotton material.The gel resin layer
Thickness be 50~80 μm.The thickness of the priming coat is 100~180 μm.The thickness of the finishing coat is 130~200 μm.
The temperature that three coatings carry out baking oven drying is 100~120 DEG C, fabric pass through the speed of baking oven be 5~
6 ms/min.The heating temperature of step (5) the heating calendering is 110~120 DEG C, and calendering pressure is 40~45 tons.The step
Suddenly the temperature of (6) calendering is 70~80 DEG C, and calendering pressure is 40~45 tons.
The present invention is beneficial to be had technical effect that:
The present invention is especially added with low polymer in coating, with low molecule material alum and brightener, makes painting canvas
There is middle layer anti-oxidation efficacy, coating not to allow fugitive color.With low molecule materials silicon dioxide, make canvas coating that there is water suction
Property, reach the soaking effect of quick-drying.The present invention is knitted using the novel of technique productions of three sprayings, two hot rollings, one of calendering
The divine force that created the universe has the characteristics that Freehandhand-drawing painting canvas and performance;Painting canvas face can also be made smooth;Calendering finishing process is finally used, coating is made
In low molecule material reach the maximum value of certain limit, painting canvas soft texture can be made.
Traditional painting canvas, can only draw oil painting, the acrylic painting in west etc., and the aqueous matt canvas of Freehandhand-drawing provided by the invention
Soft texture, good water absorption is not fastidious to dilute consistency of pigment, and cloth cover is secured, it is not easy to and jaundice hair wrinkle is suitble to outdoor suspension,
With folding crape, mould proof, Anti-moth-eating, anti-deformation, it is non-aging, be easy to mounting, be suitable for industrialized large-scaled production, color stable, have
There is many advantages, such as unique texture appearance.
Specific implementation mode
With reference to embodiment, the present invention is specifically described.

Test case 1 carries out surface observation to painting canvas:
(1) visual effect:Painting canvas surface is clean and tidy, and longitude and latitude lines is clear, shows textural effect, and apparent colour is that white is sub-
Light.Environment head-up painting canvas surface indoors, it is matt.
(2) sense of touch:Feel painting canvas longitude and latitude train of thought is clear, and painting canvas is flexible, and smoothness is moderate, there is certain resistance when streaking painting canvas
Power, but it is not unsmooth, there is heavy feeling.
Test case 2 carries out physicochemical property detection to painting canvas:Detection method and the results are shown in Table 1.
Table 1
Test case 3, practical effect:
(1) this painting canvas is used as Freehandhand-drawing painting canvas, compared with rub resistance and modification.The strong adhesive force of coating, repeatedly friction coatings do not take off
It falls.
(2) pigment and the adhesive force on painting canvas surface are also fine, if drawing very thick pigment on painting canvas surface, wait after having done
Pigment is difficult to peel off, i.e., pigment will not fall off after people draw a picture, and has ensured that the quality drawn (uses propylene oil painting etc. for artist
The performance test that pigment is drawn a picture shows).
(3) for this painting canvas to propylene, the effect of watercolor, gouache color is relatively good, painting canvas good water absorption, to dilute consistency of pigment
It is not fastidious.These three pigment can be watered in various degree when drawing a picture.
(4) painting canvas stability itself is good, will not change colour and turn to be yellow for a long time after applying paint, 40 can be kept under sunlight
It does not turn yellow (due to being Freehandhand-drawing painting canvas, works generally preserve indoors, so to the of less demanding of UV resistant).
